From Lynchburg.
Lynchburg, June 25.
--Gentlemen who left our forces Thursday, five miles beyond Salem, on the Newcastle road, says that Hunter's army came near being captured at that point, their escape being due only to the delay in the delivery of an order.
As it was, the enemy were so hard pressed that they destroyed their ammunition train which was a mile in length.
Our informant saw it blown up.
A portion of our forces are reported to have taken a large wagon train and a number of prisoners.
The enemy on their retreat destroyed Bonsack's woolen factory in Roanoke county.
